# What is the condition of maximum power transfer?

## What is the condition of maximum power transfer?

In electrical engineering, the maximum power transfer theorem states that, to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must equal the resistance of the source as viewed from its output terminals.

## What are the limitations of maximum power transfer theorem?

Limitations of Maximum Power Transfer Theorem The efficiency of this theorem is fifty percent so it is not useful for such circuits where efficiency is to be measured. This theorem works for all circuitries but device prepared according to it will have less efficiency.

Advantages - It is applicable to the elements of the network as well as to the sources. It is very useful for circuit analysis. It is utilized to convert any circuit into its Thevenin equivalent or Norton equivalent. Disadvantages - Superposition is applicable to current and voltage but not to power.

## What are the limitations of Norton's Theorem?

Limitations of Norton's Theorem

• This formula is appropriate for the linear modules like resistors.
• It's not for such modules which are not linear like diodes, the transistor.
• It also not operate for such circuitries which has magnetic locking.

## What are the limitations of reciprocity theorem?

The limitation of this theorem is that it is applicable only to single-source networks and not in the multi-source network. The network where reciprocity theorem is applied should be linear and consist of resistors, inductors, capacitors and coupled circuits. The circuit should not have any time-varying elements.
